Why use a soft starter
When an AC motor has mains power supply applied directly to the motor terminals, it will try to reach its nominal speed as quickly as possible. This results in high current draw and mechanical stress, as the motor tries to accelerate its own inertia and the driven loads inertia instantly.
Rarely do driven loads require instant acceleration.
Soft Starters, in combination with AC Electric Motors, control the acceleration during startup. This process temporarily reduces the load and torque in the powertrain of the motor. The bene t of such a process is the improved lifespan of your system as the mechanical stress on the motor and load has been reduced, as well as the electro dynamic stresses on power cables and the electrical distribution network.
Combining your electric motors with a Soft Starter not only reduces risk, breakage and maintenance downtime, but also increases your production ef ciency and results.
